Abstract

A firing mechanism for a muzzleloading rifle has a stock, a rifle barrel, a breech plug in the rearward end of said breech plug, a receiver on the stock, a bolt and hammer assembly in the receiver rearwardly of the nipple, and a trigger assembly operatively secured to the bolt and hammer assembly. An adapter element is mounted on the rearward end of the nipple and has a rearward end with an opening therein for receiving and holding a cap rifle primer. The bolt and hammer assembly has a hammer with a forward end in axial alignment with the adapter element, the forward end of the hammer terminating in a forwardly extending conical shaped firing surface to engage a rifle primer mounted within the opening at the rearward end of the adapter element.

Description

BACKGROUND OF THE INVENTION
Muzzleloading rifles typically use a percussion cap to effect firing. Percussion caps are inferior to conventional rifle primers which give superior ignition, a hotter ignition, and which are cleaner and more consistent. The hotter the ignition, the more velocity is transmitted to the projectile.
In the firearm industry, the terms "percussion caps" and "rifle primers" are well known and understood by those involved in that industry.
A percussion cap is a cup-shaped, formed piece of thin, soft metal with a thin coating of priming compound on the inside of the flat surface of the closed portion of the cup. For the priming compound to ignite, it must be compressed between two surfaces. The percussion cap is placed on the nipple, which acts as an anvil, so that when the hammer strikes the cap, the priming compound is compressed between the hammer and the nipple, setting off the priming compound. The percussion cap is used in virtually all non-flintlock muzzleloading rifles.
A rifle primer is similar in size and shape to the percussion cap, but contains significantly more priming compound. The rifle primer has an integral anvil, normally eliminating the need for a nipple. When the hammer strikes the rifle primer, the priming compound is compressed between the hammer and the integral anvil, setting off the priming compound.
It is therefore a principal object of this invention to provide a muzzleloading rifle which can utilize a rifle primer for firing rather than a conventional percussion cap.
A further object of this invention is to provide a muzzleloading rifle with components to use a rifle primer which can be easily and quickly installed in a conventional muzzleloading rifle.
A still further object of this invention is to provide a hammer for a muzzleloading rifle which is tapered to better ignite the rifle primer and which overcomes a problem with conventional firing pins which might penetrate the primer without igniting it.
These and other objects will be apparent to those skilled in the art.
BRIEF SUMMARY OF THE INVENTION
Conventional muzzleloading rifles have a breech plug at the rearward end of the rifle barrel. A conventional nipple is threaded into the rearward end of the breech plug and protrudes rearwardly into the receiver. A conventional percussion cap is placed on the rearward end of the nipple and is selectively ignited through the impact of the flat surface of the rifle hammer.
This invention eliminates the percussion cap. Instead, an adapter element is placed on the rearward end of the nipple in place of the conventional percussion cap. The adapter element has a rearward opening that is compatible in shape to a conventional rifle primer which is received therein. The hammer of the rifle has a tapered and forwardly extending conical surface terminating in a point which can selectively strike the rifle primer for ignition.

DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1 is a side elevational view of a conventional muzzleloading rifle 10, which has a stock 12, a barrel 14, a receiver 16, a trigger assembly 18, a bolt and hammer assembly 20, a hammer 22 (FIG. 2) with a flat firing surface 23, a breech plug 24 (FIG. 2) with a conventional nipple 26 threaded into the rearward end of the breech plug. The rearward end of the nipple terminates in a conventional hollow shoulder 28. The above described structure is conventional.
This invention contemplates the use of an adapter element 30 (FIGS. 4 and 5) which has a forward end 32, a rearward end 34, a forward bore 36, and a rearward bore or opening 38. The bores 36 and 38 are separated by shoulder 40, as best shown in FIG. 5.
A pair of annular grooves 42 and 44 appear concentrically on the outer surface of adapter element 30. Intersecting vertical slot 46 and horizontal slot 48 are cut in the forward end of adapter element 30 and intersect annular groove 44. The slots 46 and 48 form deformable sections 50. The adapter element 30 is fitted on the shoulder 28 of nipple 26 as shown in FIG. 3. The deformable sections 50 can be crimped inwardly against the shoulder 28 to affix the adapter element 30 to the nipple.
The conventional bolt and hammer assembly is removed from the rifle 10 and a modified bolt and hammer assembly 52 (FIGS. 3, 6 and 7) is used in lieu thereof. Bolt and hammer assembly 52 has a hammer 54 with a well 56 therein. A tapered conical firing surface 58 is concentrically located in well 56 and terminates in a forwardly extending point 60.
A conventional rifle primer 62 having a rearward flange 64 is complementary in shape and fits directly into the opening 38 at the rearward end 34 of adapter element 30 (see FIGS. 3 and 5). Typically, a plurality of primers are loaded into the adapters beforehand and are carried by the hunter.
The modified bolt and hammer assembly 52 is placed in the receiver 16 in place of the conventional bolt and hammer assembly 20. When the bolt and hammer assembly 52 is in its retracted position (FIG. 3) and with the use of suitable tools, the preloaded adapter element is placed on the rearward end of the nipple 26. When the trigger assembly 18 is conventionally actuated, the hammer 54 moves forwardly and the point 60 on the conical surface 58 engages the rifle primer 62 and causes it to ignite.
The modified hammer 54, because of the conical surface 58 at point 60 is sure to ignite the rifle primer 62. Hammer 54 is also superior to the use of a conventional firing pin because the firing pin might penetrate the primer without igniting it.
It is therefore seen that the conventional muzzleloading rifle 10 can be easily converted to use rifle primers by the addition of the adapter element 30 along with the modified hammer 54. As a result, the resulting rifle gives superior ignition, a hotter ignition, a cleaner ignition, and is more consistent. Through the use of the hotter ignition, more velocity is transmitted to the ball or slug used by the rifle 10. The modification of the existing rifle 10 can be quickly and easily accomplished.
It is therefore seen that the device of this invention will accomplish at least its stated objectives.
